TO. ALL WHOM IT MAY CONCERN:

Be it known that weTHoMAs D. McGALL and SAMUEL BUSHNELL, both of the town of Walton, in the county of Delaware, and State of'New York, have inventeda new and' improved Mode of Hanging Doors; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and .to theletters of reference marled thereon, in which- Figure 1 represents a perspective view of 'the clhsp-hingr'-" which we use,`when heldv together by-the rivet a.

' Figure 2 represents a perspectiv'fe view of the same, with the rivet a withdrawn and both sides of the hinge separated. g

:Figure 3 is an elevationo'f the entire device as applied tov a door.

The natureA of -our invention consists in hanging doors to open either way, in or out, and sc as to leave no open space between them and the jamhs to'whch they are hinged while they 4areopen.

To do this, we attach a roller or cylinder, of 'the same diameter and length as thedoor to be hung, to said door, by means of .ciasp-hinges, of suitable metal, encircling said roller or cylinder, with the ends of said hinges clasping bothsdes of the door, and screwed thereto.

` Similar clasp-hinges encircle the roller or cylinder immediately beneath the ones attached tothe door, and are attached to the jamb of` the door in a similar manner. i v

The portion of the Aroller or cylinder where these hinges encircle it has grooves cut in it all the way round, so as' to have the surface of the cylinder-even with the hinges, thereby forming shoulders-on ythe cylinder, by means of which both 4it andthe hinges are held, in position, and the cylinder left free to turn in the hinges either backward or forward, and the hinges left free toturn on the cylinder in the same manner.

The cylinder can be made of wo'od or iron. Where wood is used, the grooves or seats in which the hinges work should be metaLIined. l v

The hinges are4 made in two sections, and form a joint when put together, and are fastened by a; rivet, for the purpose of enabling them to be put upon the lcylinder, in the grooves made Atherein to receive them, and the edge of the door 'next Vthe cylinder is hollowed out, to form an arc similar to the periphery of the cylinder, so that the door can lie Aclose to it, and swingaround .on'it or with it freely.

' The following is ade'scription of the accompanying drawings:

E, fig. 3, is the roller or cylinder. v

s s are the clasp-hinges, by which it is attached to the door, D, and

n n are. similar hinges,'by which-it is attached to the jamb, J.

g g represent the grooves, in which the hinges work, and by means of which both the hinges and cylinder are held in their proper position. i

a, iig. 1, represents the rivet, by which both sections of the hinge are connected.

What we cla-im as our invention, and desire to secure by Letters Patent, 'is- The clasp-hinges s s and nn, with their joints, a, and the revolving cylinder e, with its grooves g g,'. when constructed, combined, and arranged in the manner und to operate substantially as described.
